Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

readOnlyHint=true already declares the safe-read profile, so the description only needs to add context beyond that. It notes the pagination mechanism and maps to the underlying GET endpoint, which is modestly useful, but says nothing about result ordering, page size defaults, or empty-result behavior. Adequate but thin on top of the annotation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, front-loaded with the core purpose and free of filler. The trailing endpoint reference is mildly redundant for an agent that already has the tool name, but it is short and does not bloat the definition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a no-required-param, read-only list tool with fully documented schema and no output schema, the description covers what is needed to invoke it correctly. Pagination is acknowledged and the safety profile is carried by annotations; only return-shape details are absent, which is minor here.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all four parameters (after, limit, before, subdomain) are already documented in the schema. The description's mention of before/after cursors repeats what the schema says without adding format or interaction detail. Baseline 3 applies when the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: 'List the metrics configured on a status page.' An agent can distinguish this from the incident/service siblings since the resource (metrics) is unique. It stops short of explicitly contrasting with any sibling, but the purpose itself is unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The only guidance given is 'Use `before`/`after` cursors to paginate,' which is parameter mechanics rather than when-to-use guidance. There is no statement of when this tool is appropriate versus the sibling list/get tools, nor any prerequisites or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
